C. 20554 News Media Information 202 / 418- 0500 Internet: http:// www. fcc. gov TTY: 1- 888- 835- 5322 DA 06- 202 February 3, 2006 THE FCC’S ADVISORY COMMITTEE FOR THE 2007 WORLD RADIOCOMMUNICATION CONFERENCE APPROVES RECOMMENDATIONS ON WRC- 07 ISSUES IB Docket No. 04- 286 On January 25, 2006, the World Radiocommunication Conference Advisory Committee (WRC- 07 Advisory Committee) approved recommendations to the Commission on a number of issues that will be considered by the 2007 World Radiocommunication Conference (WRC- 07). The WRC- 07 Advisory Committee was established by the Commission in January 2004 to assist it in the development of proposals for WRC- 07. To that end, the WRC- 07 Advisory Committee has forwarded the recommendations it has developed since the beginning of 2004 to the Commission for consideration. We appreciate the substantial amount of work that the WRC- 07 Advisory Committee has put into developing its recommendations. We have attached to this Public Notice the WRC- 07 Advisory Committee’s recommendations that were approved at the January 25, 2006 meeting and request comments on these recommendations. Based upon our initial review of the recommendations forwarded to the Commission, the International Bureau in coordination with other Commission Bureaus and Offices tentatively concludes that we can generally support the attached WRC- 07 Advisory Committee recommendations. We seek comments on the recommendations that appear in all of the WRC- 07 Advisory Committee documents and on our initial impressions. In addition, the National Telecommunications and Information Administration (NTIA) has provided to the Commission draft preliminary views and proposals that have been developed by the Executive Branch Agencies. We also request comments on these documents. The comments provided will assist the FCC in its upcoming consultations with the U. S. Department of State and NTIA in the development of U. S. positions for WRC- 07. The recommendations that are attached to this Public Notice may evolve in the course of interagency discussions as we approach WRC- 07 and, therefore, do not constitute a final U. S. Government position on any issue. The complete text of these recommendations is also available in the FCC’s Reference Information Center, Room CY- A257, 445 12 th Street, SW, Washington, DC 20554 or by accessing the FCC’s WRC- 07 world wide web site at: http:// www. fcc. gov/ wrc- 07.

Recommendations by the Advisory Committee for the 2007 World Radiocommunication Conference: INFORMAL WORKING GROUP 1 (IWG- 1) Terrestrial and Space Science Services Document WAC/ 086( 25.01.06): DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda Item 1.2 (Res 746): to consider allocations and regulatory issues related to the Earth exploration- satellite (passive) service, space research (passive) service and the meteorological satellite service in accordance with Resolutions 746 (WRC- 03) and 742 (WRC- 03); Background Information: This proposal addresses resolves 1 of Resolutions 746 (WRC- 03), “to invite ITU- R to conduct sharing analyses between geostationary meteorological satellites operating in the space- to- Earth direction and the fixed, fixed-satellite and mobile services in the band 18.0- 18.4 GHz to define appropriate sharing criteria with a view to extending the current 18.1- 18.3 GHz geostationary meteorological satellite allocation in the space- to- Earth direction to 300 MHz of contiguous spectrum.” Presently the meteorological- satellite (MetSat) service (space- to- Earth), limited to the geostationary- satellite orbit (GSO), is allocated by footnote 5.519 in the band 18.1- 18.3 GHz. The band is allocated on a primary basis to the fixed- satellite service (FSS), the fixed service and the mobile service in all three Regions and these allocations also exist for these same services in the band 17.8- 18.1 GHz in all Regions. In both bands, the FSS is allocated in both the space- to- Earth and Earth- to- space directions. Additionally, in the 18.1- 18.4 GHz band, the FSS (space- to- Earth) allocation has associated with it Nos. 5.484A and 5.516B. The first provision applies to non- Geostationary FSS satellite systems. The latter provision states that the band 18.3- 19.3 GHz has been identified for use by high- density applications in the FSS in Region 2. WP- 7B has been the lead ITU- R group concerned with analyzing the sharing potential with other services in the band and it has exchanged several Liaison Statements with WP-4A. As a consequence of the information provided by WP- 4A, those involved in the design of the next generation GSO meteorological satellites have optimized the design to maximize the level of homogeneity between FSS and Metsat systems. It is envisioned that this would maximize compatibility and facilitate coordination under No. 9.7 for operation of both types of systems in the space- to- Earth direction. In accordance with No. 5.516 the band 18.0- 18.1 GHz in the Earth- to- space direction is used for feeder links for the broadcasting- satellite service. Compatibility studies have been performed to estimate the typical required separation distances in reverse band sharing situations between receiving MetSat earth stations and transmitting BSS feeder uplink stations. In the worst case, it has been determined that around 40 km separation is required. Therefore it is expected that with some care in situating the limited number of MetSat receive stations international coordination would rarely be required under No. 9.17A. 3 5 USA/ /2 MOD 15. 4- 18.4 GHz Allocation to services Region 1 Region 2 Region 3 15. 4- 15.43 AERONAUTICAL RADIONAVIGATION 5.511D 15. 43- 15. 63 FIXED- SATELLITE (Earth- to- space) 5. 511A AERONAUTICAL RADIONAVIGATION 5.511C 15. 63- 15. 7 AERONAUTICAL RADIONAVIGATION 5.511D 15. 7- 16. 6 RADIOLOCATION 5.512 5. 513 16. 6- 17. 1 RADIOLOCATION Space research (deep space) (Earth- to- space) 5.512 5. 513 17. 1- 17. 2 RADIOLOCATION 5.512 5. 513 17.2- 17.3 EARTH EXPLORATION- SATELLITE (active) RADIOLOCATION SPACE RESEARCH (active) 5. 512 5.513 5.513A 17. 3- 17. 7 FIXED- SATELLITE (Earth- to- space) 5.516 (space- to- Earth) 5.516A 5.516B Radiolocation 17. 3- 17. 7 FIXED- SATELLITE (Earth- to- space) 5.516 BROADCASTING- SATELLITE Radiolocation 17. 3- 17. 7 FIXED- SATELLITE (Earth- to- space) 5.516 Radiolocation 5.514 5.514 5. 515 5. 517 5.514 17. 7- 18. 1 FIXED FIXED- SATELLITE (space- to- Earth) 5.484A (Earth- to- space) 5.516 MOBILE ADD 5. 519 5.

In addition, 5. Metsat ensures that Metsat receive stations cannot affect the App 30A Plan. 6 9 Reasons: Consequential modification to the additional allocation to MetSat in the band 18.0- 18.1 GHz. ITU studies have shown that extending the ±8º coordination arc, currently applicable to FSS networks in this band, to the meteorological- satellite (MetSat) services in this band would reduce the workload of the Bureau in identifying affected administrations and the number of unnecessary coordinations for such systems while maintaining the rights of administrations to be included in requests for coordination involving the MetSat or FSS service in this band. _______________ 9 10 INFORMAL WORKING GROUP 4 (IWG- 4) Broadcasting and Amateur Issues Document WAC/ 083( 25.01.06): DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE Agenda Item 1.6 (Res. 414): to consider additional allocations for the aeronautical mobile (R) service in parts of the bands between 108 MHz and 6 GHz, in accordance with Resolution 414 (WRC- 03) and, to study current satellite frequency allocations, that will support the modernization of civil aviation telecommunication systems, taking into account Resolution 415 (WRC- 03); Background Information: This proposal considers additional allocations for the aeronautical mobile (R) service (AM( R) S ) in parts of the bands between 108 MHz and 6 GHz, in accordance with Resolution 414 (WRC- 03). Existing AM( R) S bands are nearing saturation in high traffic areas. In addition, new applications and concepts in air traffic management put further pressure on existing AM( R) S bands. Resolution 414 (WRC- 03) states that new technologies to support air navigation may not conform to the definition of aeronautical radionavigation in the Radio Regulations. WRC- 03 provided a mechanism to implement these new aviation technologies by adding AM( R) S use in the band 108 - 117.975 MHz by footnote 5.197A in accordance with Resolution 413 (WRC- 03). One emerging application driving requirements for new AM( R) S spectrum is the integration of command and control for unmanned aircraft (UA) into air traffic services (ATS) airspace. Conversely, AM( R) S spectrum is not appropriate for UA payload data use, such as downlinking information and operational data from the UA. ITU- R Working Party 8B (WP 8B) and the International Civil Aviation Organization (ICAO) developed a draft operational concept, and technology selection criteria and procedures for new aviation technology. WP 8B and ICAO determined that the new aviation systems require two distinct categories of AM( R) S spectrum. The first category for surface applications could support high data throughput over moderate transmission distances. There is a high degree of reuse of this spectrum. For surface applications, ICAO and WP8B recommended 5 091 - 5 150 MHz as a suitable band. WP 8B is also studying the band 5 091- 5 150 MHz under agenda item 1.5 for the purpose of aeronautical mobile telemetry applications. 1 The second category for bidirectional air to ground applications could support a moderate data throughput over longer propagation distances out to radio line- of- sight. These applications require a number of distinct channels to allow for sector- to- sector assignments. For radio line-of- sight applications, ICAO and WP 8B recommended 960 - 1 024 MHz as a suitable band. 1 Note that frequencies in the band 108- 117.975 MHz are not currently being considered by the U. S. for new aviation technology. 10 11 Proposal: USA/ / 1 MOD 890- 1 300 MHz Reasons: To provide allocations to support evolving AM( R) S applications.

Marrakesh, 2002) of the Plenipotentiary Conference: “Advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks” in accordance with Resolution 86 (WRC- 03); Background information: Resolution 86 (Rev. Marrakesh, 2002) requested that WRC- 03 and subsequent Conferences review the regulatory procedures associated with the advance publication, coordination, notification and recording of frequency assignments pertaining to satellite networks. WRC- 03 identified in Resolution 86 (WRC- 03) the scope and the criteria to be used for the implementation of Resolution 86 (Rev. Marrakesh, 2002). Resolves 1 of Resolution 86 (WRC- 03) specifically states that WRC- 07 should “consider any proposals which deal with deficiencies in the advance publication, coordination, notification and recording procedures of the Radio Regulations (RR) for space services which have either been identified by the Board and included in the Rules of Procedure or which have been identified by administrations or by the Bureau as appropriate.” Currently, Appendix 4 makes certain data elements optional for the case of “Advance publication of a non- geostationary- satellite network not subject to coordination under Section II of Article 9”. These fields include i) the necessary bandwidth; ii) the carrier frequency or frequencies of the emission; iii) the maximum value of the peak envelope power, in dBW, supplied to the input of the antenna for each carrier type; iv) the minimum value of the peak envelope power, in dBW, supplied to the input of the antenna for each carrier type; v) the minimum power density, in dB( W/ Hz), supplied to the input of the antenna for each carrier type; and vi) the required C/ N ratio. This information is required in order to determine whether unacceptable interference may be caused by the planned satellite network or system and communicate this information to the publishing administration and the Bureau under No. 9.3. To only require this information at the notification stage makes any analysis too late to benefit either administration. While most administrations have been supplying this data as part of the Advance Publication Information (API), there have been instances where the information was not made available. Therefore modifications to Appendix 4 are necessary to allow necessary analysis to take place during API. 15 16 Proposal APPENDIX 4 ANNEX 2 Characteristics of satellite networks, earth stations or radio astronomy stations USA/ /1 MOD Table of characteristics to be submitted for space and radio astronomy services (WRC- 0307) Items in Appendix C _ CHARACTERISTICS TO BE PROVIDED FOR EACH GROUP OF FREQUENCY ASSIGNMENTS FOR A SATELLITE ANTENNA BEAM OR AN EARTH STATION OR RADIO ASTRONOMY ANTENNA Advance publication of a non- geostationary- satellite network not subject to coordination under Section II of Article 9 NECESSARY BANDWIDTH AND CLASS OF EMISSION C. 7 (in accordance with Article 2 and Appendix 1) the necessary bandwidth and the class of emission: for each carrier C. 7. a In the case of Appendix 30B, required only for notification under Article 8 OX 3 C. 7. b the carrier frequency or frequencies of the emission( s) OX 3 C. 8 POWER CHARACTERISTICS OF THE TRANSMISSION C. 8. a For the case where individual carriers can be identified: the maximum value of the peak envelope power, in dBW, supplied to the input of the antenna for each carrier type C. 8. a. 1 Required if C. 8. b. 1 is not provided O+ 3 the maximum power density, in dB( W/ Hz), supplied to the input of the antenna for each carrier type 2 C. 8. a. 2 Required if C. 8. b. 2 is not provided + C. 8. b For the case where it is not appropriate to identify individual carriers: the total peak envelope power, in dBW, supplied to the input of the antenna For coordination or notification of an Appendix 30A earth station the values shall include the maximum range of power control C. 8. b. 1 Required if C. 8. a. 1 is not provided O+ 3 the maximum power density, in dB( W/ Hz), supplied to the input of the antenna 2 For coordination or notification of an Appendix 30A earth station the values shall include the maximum range of power control C. 8. b. 2 Required if C. 8. a. 2 is not provided + 16 17 the minimum value of the peak envelope power, in dBW, supplied to the input of the antenna for each carrier type C. 8. c. 1 If not provided, the reason for absence under C. 8. c. 2 O+ 3 C. 8. c. 2 if C. 8. c. 1 is not provided, the reason for absence of the minimum value of the peak envelope power + 3 the minimum power density, in dB( W/ Hz), supplied to the input of the antenna for each carrier type 2 C. 8. c. 3 If not provided, the reason for absence under C. 8. c. 4 O+ 3 C. 8. c. 4 if C. 8. c. 3 is not provided, the reason for absence of the minimum power density + 3 for space- to- Earth, Earth- to- space or space- to- space links. for each carrier type, the greater of either the carrier- to- noise ratio, in dB, required to meet the performance of the link under clear- sky conditions or the carrier- to- noise ratio, in dB, required to meet the short- time objectives of the link inclusive of necessary margins C. 8. e. 1 If not provided, the reason for absence under C. 8. e. 2 O+ 3 C. 8. e. 2 if C. 8. e. 1 is not provided, the reason for absence of the carrier- to- noise ratio + 3 3 This item is optional for amateur satellite frequency assignments.

Document WAC/ 085( 25.01.06): DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE Agenda Item 7.2 to recommend to the Council items for inclusion in the agenda for the next WRC, and to give its views on the preliminary agenda for the subsequent conference and on possible agenda items for future conferences, taking into account Resolution 802 (WRC- 03), Background Information: In the Preliminary Agenda for WRC- 2010, agenda item 2.2 states: “to consider frequency allocations between 275 GHz and 3 000 GHz taking into account the result of ITU- R studies in accordance with Resolution 950 (WRC- 03);” Studies in the ITU- R, most notably WP1A, WP3J, WP3M, WP4A, WP7B, WP7C, WP7D, WP8A, WP9B, have very clearly identified the interest within the active and passive services in using frequencies in the spectral region above 275 GHz. Resolution 950 (WRC- 03) has allowed for the submission of details on systems operating in this range into the Master International Frequency Register (MIFR). However, there is no registered use to date by any of the active services. On the other hand, the radio astronomy, Earth exploration- satellite (passive) and the space research (passive) services all make extensive use of this spectral region. Within the radio astronomy service, several administrations have already made significant infrastructure investments in radio astronomy sites around the world. This extensive use of this spectral region by the passive services along with the lack of use of the same by the various active services indicates that the general consideration of frequency allocations between 275 and 3000 GHz is premature and such consideration would likely take up a great deal of resources in preparing for 17 18 the 2010 Conference. As an alternative, reviewing and revising No. 5.565 would be desirable while at the same time require far less preparation by administrations for the 2010 Conference. Proposal: USA/ / 1 MOD RESOLUTION 803 (WRC- 0307) Preliminary Aagenda for the 2010 World Radiocommunication Conference The World Radiocommunication Conference (Geneva, 20037), USA/ / 2 SUP 2.2 to consider frequency allocations between 275 GHz and 3 000 GHz taking into account the result of ITU- R studies in accordance with Resolution 950 (WRC- 03); USA/ / 3 ADD 2. X to review and revise No. 5.565 with a view to updating the list of frequencies for passive services in the spectral region from 275 – 3000 GHz, taking into account the results of ITU- R studies in accordance with Resolution 950. Reasons: The extensive use of this spectral region by the passive services along with the lack of use of the same by the various active services indicates that the general consideration of frequency allocations between 275 and 3000 GHz is premature and such consideration would likely take up a great deal of resources in preparing for the 2010 Conference. As an alternative, reviewing and revising No. 5.565 would be desirable while at the same time require far less preparation by administrations for the 2010 Conference.

Draft Proposals on WRC- 07 Agenda Items received from the National Telecommunications and Information Administration (NTIA): Document WAC/ 075( 25.01.06): DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE Agenda Item 1.2 (Res 746): to consider allocations and regulatory issues related to the Earth exploration- satellite (passive) service, space research (passive) service and the meteorological satellite service in accordance with Resolutions 746 (WRC- 03) and 742 (WRC- 03); Background Information: This proposal addresses resolves 1 of Resolutions 746 (WRC- 03), “to invite ITU- R to conduct sharing analyses between geostationary meteorological satellites operating in the space- to- Earth direction and the fixed, fixed- satellite and mobile services in the band 18.0- 18.4 GHz to define appropriate sharing criteria with a view to extending the current 18.1- 18.3 GHz geostationary meteorological satellite allocation in the space- to- Earth direction to 300 MHz of contiguous spectrum.” Presently the meteorological- satellite (MetSat) service (space- to- Earth), limited to the geostationary- satellite orbit (GSO), is allocated by footnote 5.519 in the band 18.1- 18.3 GHz. The band is allocated on a primary basis to the fixed- satellite service (FSS), the fixed service and the mobile service in all three Regions and these allocations also exist for these same services in the band 17.8- 18.1 GHz in all Regions. In both bands, the FSS is allocated in both the space- to- Earth and Earth-to- space directions. Additionally, in the 18.1- 18.4 GHz band, the FSS (space- to- Earth) allocation has associated with it Nos. 5.484A and 5.516B. The first provision applies to non- Geostationary FSS satellite systems. The latter provision states that the band 18.3- 19.3 GHz has been identified for use by high- density applications in the FSS in Region 2. WP- 7B has been the lead ITU- R group concerned with analyzing the sharing potential with other services in the band and it has exchanged several Liaison Statements with WP- 4A. As a consequence of the information provided by WP- 4A, those involved in the design of the next generation GSO meteorological satellites have optimized the design to maximize the level of homogeneity between FSS and Metsat systems. It is envisioned that this would maximize compatibility and facilitate coordination under No. 9.7 for operation of both types of systems in the space- to- Earth direction. In accordance with No. 5.516 the band 18.0- 18.1 GHz in the Earth- to- space direction is used for feeder links for the broadcasting- satellite service. Compatibility studies have been performed to estimate the typical required separation distances in reverse band sharing situations between receiving MetSat earth stations and transmitting BSS feeder uplink stations. In the worst case, it has been determined that around 40 km separation is required. Therefore it is expected that with some care in situating the limited number of MetSat receive stations international coordination would rarely be required under No. 9.17A. While the expected design of the GSO MetSat satellite networks envisioned for operation in the 300 MHz wide band appears to be generally compatible with FSS systems being implemented, it would appear that, for Region 2, operating MetSat systems below 18.3 GHz would avoid several potential difficulties. Given the desire to have a common MetSat allocation in all three Regions, it is proposed 22 24 18. 10- 18.4 FIXED FIXED- SATELLITE (space- to- Earth) 5.484A 5.516B (Earth- to- space) 5.520 MOBILE MOD 5. 519 5.521 Reasons: Consequential changes due to the modification of No. 5.519. 24 26 Document WAC/ 082( 25.01.06): DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda Item 1.3: in accordance with Resolution 747 (WRC- 03), consider upgrading the radiolocation service to primary allocation status in the bands 9 000 - 9 200 MHz and 9 300 - 9 500 MHz, and extending by up to 200 MHz the existing primary allocations to the Earth exploration- satellite service (active) and the space research service (active) in the band 9 500 - 9 800 without placing undue constraint on the services to which the bands are allocated. Background Information: The proposal addresses the upgrade of radiolocation service in the band 9 000- 9 200 MHz and 9 300- 9 500 MHz. As identified in Resolution 747 (WRC- 03), there is a need to provide contiguous primary spectrum around the 9 GHz band in order for existing and planned radiolocation systems to satisfy their required missions. Changes in technology and emerging requirements for increased image resolution and increased range accuracy necessitate wider contiguous emission bandwidths. Therefore, there is a need to upgrade the status of frequency allocations to the radiolocation service in the frequency range 9 000 - 9 200 MHz and 9 300 - 9 500 MHz. The bands 9 000 - 9 200 MHz and 9 300 - 9 500 MHz are allocated on a primary basis to aeronautical radionavigation and radionavigation, respectively. The Radio Regulation No. 4.10 recognizes radionavigation as a safety service. The radiolocation services and the radionavigation service have demonstrated compatible operations over many years through the use of similar system characteristics such as low- duty cycle emissions, scanning beams and interference reduction techniques. For example, past operational experience in the 2 900- 3 100 MHz band as found in Report ITU- R M. 2032 “Tests illustrating the compatibility between maritime radionavigation radars and emissions from radiolocation radars in the band 2 900 - 3 100 MHz” confirms that it is possible to mitigate interference from radiolocation radars to maritime radionavigation radars in the band. Some studies have been completed within ITU- R WP 8B that characterize the technical performance and protection criteria of radiolocation and radionavigation systems that ensure compatible operations in the bands 9 000 - 9 200 MHz and 9 300 - 9 500 MHz. Recommendation ITU- R M. 1313 contains the technical characteristics and protection criteria for maritime radars in the band 9 300 - 9 500 MHz and that Recommendation ITU- R M. 1372 identifies interference reduction techniques which enhance compatibility among radar systems. The ITU- R studies that have been completed so far, such as on maritime radionavigation radars and emissions from radiolocation radars in the band 9 200 – 9 500 MHz illustrate compatibility between the two services in this band and are an indicator of how the sharing would be with other radionavigation systems. These studies indicate that typical maritime radionavigation radars can suppress emissions from other radars, even when the maritime radars receive interference with very high interference- to- noise (I/ N) ratios if the unwanted pulsed waveform is asynchronous and has a low effective duty cycle. These study results support the successful historical sharing experience between the two services in the 9 200- 9 500 MHz band. As most maritime radars in the 9 000 - 9 500 MHz bands are very similar in design and operation, one 26 27 does not expect a great variation from the protection criteria that was derived from the radars that were used for these studies. Therefore, there is an indication that the results could apply to other similar radars that operate in the 9 000 - 9 500 MHz bands as well. Therefore a primary allocation for radiolocation can be added to the 9 000 - 9 200 and 9 300 - 9 500 MHz bands.

USA/ /02 MOD 5.475 The use of the band 9 300- 9 500 MHz by the aeronautical radionavigation service is limited to airborne weather radars and ground- based radars. In addition, ground- based radar beacons in the aeronautical radionavigation service are permitted in the band 9 300- 9 320 MHz on condition that harmful interference is not caused to the maritime radionavigation service. In the band 9 300- 9 500 MHz, ground based radars used for meteorological purposes have priority over other radiolocation devices. Reasons: Priority of the meteorological ground- based radars will be covered under the new footnote 5.[ 9GHZ]. 27 28 USA/ /03 ADD 5.[ 9GHZ] In the bands 9 000 - 9 200 MHz and 9 300 - 9 500 MHz, stations operating in the radiolocation service shall not cause harmful interference to, nor claim protection from systems operating in the aeronautical radionavigation service (9 000 - 9 200 MHz) or in the radionavigation service (9 300 - 9 500 MHz). In the 9 300 - 9 500 MHz band, ground- based radars used for meteorological purposes have priority over other radiolocation uses. Reasons: Provide primary allocation to the radiolocation service, contiguous across 8 500 – 10 000 MHz, with sufficient bandwidth to meet emerging requirement for increased image resolution and increased range accuracy. The radionavigation service and the meteorological ground- based radars will continue to be protected from stations of the radiolocation service. Document WAC/ 080( 25.01.06): DRAFT PROPOSALS FOR THE WORK OF THE CONFERENCE Agenda Item 1.6 (Res. 414): to consider additional allocations for the aeronautical mobile (R) service in parts of the bands between 108 MHz and 6 GHz, in accordance with Resolution 414 (WRC- 03) and, to study current satellite frequency allocations, that will support the modernization of civil aviation telecommunication systems, taking into account Resolution 415 (WRC- 03); Background Information: This proposal considers additional allocations for the aeronautical mobile (R) service (AM( R) S ) in parts of the bands between 108 MHz and 6 GHz, in accordance with Resolution 414 (WRC- 03). Existing AM( R) S bands are nearing saturation in high traffic areas. In addition, new applications and concepts in air traffic management put further pressure on existing AM( R) S bands. Resolution 414 (WRC- 03) states that new technologies to support air navigation may not conform to the definition of aeronautical radionavigation in the Radio Regulations. WRC- 03 provided a mechanism to implement these new aviation technologies by adding AM( R) S use in the 108- 117.975 MHz band by footnote 5.197A. One emerging application driving requirements for new AM( R) S spectrum is the integration of command and control for unmanned aircraft (UAs) into air traffic services (ATS) airspace. Conversely, AM( R) S spectrum is not appropriate for UA payload data use, such as downlinking information and operational data from the UA. ITU- R Working Party 8B (WP8B) and the International Civil Aviation Organization (ICAO) developed a draft operational concept, and technology selection criteria and procedures for new aviation technology. WP8B and ICAO determined that the new aviation systems require two distinct categories of AM( R) S spectrum. The first category for surface applications could support high data throughput over moderate transmission distances. There is a high degree of reuse of this spectrum. For surface applications, ICAO and WP8B recommended 5 091- 5 150 MHz as a suitable band. WP8B is also studying the band 5 091- 5 150 MHz under agenda item 1.5 for the purpose of aeronautical mobile telemetry applications. The second category for bidirectional air to ground applications could support a moderate data throughput over longer propagation distances out to radio line- of- sight. These applications 28 29 require a number of distinct channels to allow for sector- to- sector assignments. For radio line-of- sight applications, ICAO and WP8B recommended 960- 1 024 MHz as a suitable band.

Document WAC/ 076( 25.01.06): DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE Agenda Item 1.12: to consider possible changes in response to Resolution 86 (Rev. Marrakesh, 2002) of the Plenipotentiary Conference: “Advance publication, coordination, notification and recording procedures for frequency assignments pertaining to satellite networks” in accordance with Resolution 86 (WRC- 03); Background information: Resolution 86 (Rev. Marrakesh, 2002) requested that WRC- 03 and subsequent Conferences review the regulatory procedures associated with the advance publication, coordination, notification and recording of frequency assignments pertaining to satellite networks. WRC- 03 identified in Resolution 86 (WRC- 03) the scope and the criteria to be used for the implementation of Resolution 86 (Rev. Marrakesh, 2002). Resolves 1 of Resolution 86 (WRC- 03) specifically states that WRC- 07 should “consider any proposals which deal with deficiencies in the advance publication, coordination, notification and recording procedures of the Radio Regulations (RR) for space services which have either been identified by the Board and included in the Rules of Procedure or which have been identified by administrations or by the Bureau as appropriate.” Currently, Appendix 4 makes certain data elements optional for the case of “Advance publication of a non- geostationary- satellite network not subject to coordination under Section II of Article 9”. These fields include i) the necessary bandwidth; ii) the carrier frequency or frequencies of the emission; iii) the maximum value of the peak envelope power, in dBW, supplied to the input of the antenna for each carrier type; iv) the minimum value of the peak envelope power, in dBW, supplied to the input of the antenna for each carrier type; v) the minimum power density, in 32 33 dB( W/ Hz), supplied to the input of the antenna for each carrier type; and vi) the required C/ N ratio. This information is required in order to determine whether unacceptable interference may be caused by the planned satellite network or system and communicate this information to the publishing administration and the Bureau under No. 9.3. To only require this information at the notification stage makes any analysis too late to benefit either administration. While most administrations have been supplying this data as part of the Advance Publication Information (API), there have been instances where the information was not made available. Therefore modifications to Appendix 4 are necessary to allow necessary analysis to take place during API.

Not all studies in the Annexes were completed prior to WRC– 03. On the basis of Recommendation SM. 1633 and associated studies, WRC- 03 adopted Resolutions 739 and 740. Resolution 739 contains guidance to administrations operating space and radio astronomy stations in the band pairs contained in Tables 1- 1 and 1- 2, in order to come to acceptable solutions regarding space station unwanted emissions at a radio astronomy station. The Resolution includes a consultation process adopted at WRC- 03 to assist administrations in reaching mutually acceptable solutions when unwanted emissions from space services exceed specified levels in certain radio astronomy bands. The consultation process is included in Resolution 739 and it will not be considered at WRC- 07. Resolution 740 calls for the completion of studies for the band pairs indicated in its associated band-pair Table. Comprehensive studies were needed to determine whether any of the band pairs from the Table of Resolution 740 should be added to the tables in Resolution 739, taking into consideration the impact on all the concerned active and passive services, and to determine the appropriate threshold levels for consultation. In accordance with the resolves 1 of the Resolution 740, only the band pairs listed in the Table of Resolution 740 will be considered by WRC- 07. Studies have been conducted in TG 1/ 9 on a number of the band pairs listed in Resolution 740, and it is proposed at WRC- 07 to add these band pairs to Table 1- 2 of the Annex to Resolution 739. In a number of instances, existing NGSO systems already comply with the limits; systems that do not comply but that are already operating, or that have been advanced published prior to the entry in force of the Final Acts of, either WRC- 03 or WRC- 07, depending on the band (see resolves 5 of the proposed draft revision of Resolution 739), are clearly grandfathered under the terms of Resolution 739, and are not subject to the consultation process. Studies carried out in TG 1/ 9 have been documented in the appropriate Annexes of ITU- R Recommendation SM. 1633, and, for some satellite systems, indicate levels of unwanted emissions in radio astronomy bands that will not be exceeded. 35 36 Proposal: USA/ /1 (MOD) RESOLUTION 739 (REV.

It is envisioned that future exploration missions to the Moon and Mars will be robotic for the foreseeable future and manned in the long- term. Prior to 2015, there will be extensive robotic missions, examining the lunar terrain, environment and potential landing sites. To support the SRS missions in near Earth orbit, including missions in transit to the moon and at or near the moon, downlink (space- to- Earth) transmissions will operate in the 25.5- 27.0 GHz SRS allocation. This 1.5 GHz wide downlink band will be used for both scientific data retrieval and voice/ video communication with the Earth. However, there is a need for a companion uplink (Earth- to- space) band to provide the mission data, command and control links for these missions. Due to the potential for many concurrent exploration related systems and the large bandwidth requirements of these systems, especially those supporting manned missions, it is envisioned that a total uplink bandwidth of up to 500 MHz will be needed. The 22.55- 23.55 GHz band is used by tracking and data relay satellite systems to communicate with user satellites (forward links) via an existing primary inter- satellite service allocation. These forward links are paired with inter- satellite return links in the 25.25- 27.5 GHz band. In addition, the 22.55- 23.55 GHz band is both far enough from the 25.5- 27.0 GHz band to provide adequate frequency separation and wide enough to accommodate a 500 MHz sub- band, while allowing adequate bandwidth to protect existing systems. Thus the 22.55- 23.55 GHz band is the logical companion band to provide the necessary uplink bandwidth and by using the same band as for communication in the Earth- to- space direction, it provides a degree of redundancy and coverage that may prove vital for future missions. Proposal: USA/ / 1 MOD RESOLUTION 803 (WRC- 0307) Preliminary Aagenda for the 2010 World Radiocommunication Conference The World Radiocommunication Conference (Geneva, 20037), 74 75 USA/ / 2 ADD 2. XB to consider the addition of up to a 500 MHz primary space research service (Earth- to-space) allocation in the 22.55- 23.55 GHz band, taking into account the results of ITU- R studies and recognizing the need to protect existing systems in the band. Reasons: Allocating sufficient primary space research service frequency spectrum in the 22.55- 23.55 GHz band will provide the space exploration initiatives adequate uplink (Earth- to- space) bandwidth capacity in a band that is linked for the inter- satellite service and thus is a reasonable companion to the primary space research service 25.5- 27.0 GHz space- to- Earth band. USA/ / 3 ADD RESOLUTION USXXX (WRC- 07) Use of the Band 22.55- 23.55 GHz by the Space Research Service The World Radiocommunication Conference (Geneva, 2007), considering a) that there is growing interest by space agencies around the World in the comprehensive exploration of the Moon; b) that the lunar exploration missions, examining the terrain, environment and potential landing sites, will be robotic for the foreseeable future and manned in the long- term; c) that a primary space research service (space- to- Earth) allocation in the band 25.5- 27.0 GHz was added to the Table of Allocations to support a wide range of space research missions; d) that space research service (space- to- Earth) transmissions in the 25.5- 27.0 GHz band will be used to support space research service missions in near Earth orbit, including missions in transit to the moon and at or near the moon; e) that the space research service (space- to- Earth) transmissions in the 25.5- 27.0 GHz band will be used for both scientific data retrieval and voice/ video communication with the Earth; f) that there is a need for a companion uplink space research service (Earth- to- space) band to provide the mission data, command and control links for the lunar exploration missions; g) that due to the potential for many concurrent exploration related systems and the large bandwidth requirements of these systems, especially those supporting manned missions, it is 75 76 envisioned that a total uplink bandwidth of up to 500 MHz will be needed; h) that the 22.55- 23.55 GHz band is both far enough from the 25.5- 27.0 GHz band to provide adequate frequency separation and wide enough to accommodate a 500 MHz sub- band, while allowing adequate bandwidth to protect existing systems; i) that the 22.55- 23.55 GHz band is used by tracking and data relay satellite systems to communicate with user satellites (forward links) via the existing primary inter- satellite service allocation; j) that the 22.55- 23.55 GHz band is the logical companion band to provide the necessary uplink bandwidth and by using the same band as for communication in the Earth- to- space direction, it provides a degree of redundancy and coverage that may prove vital for future missions; recognizing 1 that the band 22.55- 23.55 GHz is allocated to the fixed, inter- satellite and mobile services; 2 that the inter- satellite forward links in the 22.55- 23.55 GHz band are paired with inter- satellite return links in the 25.25- 27.5 GHz band; 3 that sharing between space research service (Earth- to- space) and the fixed, inter- satellite and mobile services may be feasible in the band 22.55- 23.55 GHz; resolves 1 to invite ITU- R to conduct sharing analyses between space research service systems operating in the Earth- to- space direction and the fixed, inter- satellite and mobile services in the band 22.55- 23.55 GHz to define appropriate sharing criteria with a view to allocating up to 500 MHz in the band 22.55- 23.55 GHz for the space research service in the Earth- to- space direction; 2 to recommend that WRC- 10 review the results of the studies under resolves 1 and consider the inclusion of the sharing criteria within the Radio Regulations and appropriate modifications to the Table of Frequency Allocations, based on proposals from administrations; invites administrations to contribute to the sharing studies between the space research service and the fixed, inter-satellite and mobile services in the 22.55- 23.55 GHz band; invites ITU- R 76 77 to complete the necessary studies, as a matter of urgency, taking into account the present use of the allocated band, with a view to presenting, at the appropriate time, the technical information likely to be required as a basis for the work of the Conference; instructs the Secretary- General to bring this Resolution to the attention of the international and regional organizations concerned. Reasons: Consequential change required by the addtion of new agenda item 2. XB to the Agenda for WRC- 10. Document WAC/ 078( 25.01.06) – Proposal 2: DRAFT PROPOSAL FOR THE WORK OF THE CONFERENCE Agenda Item 7.2 to recommend to the Council items for inclusion in the agenda for the next WRC, and to give its views on the preliminary agenda for the subsequent conference and on possible agenda items for future conferences, taking into account Resolution 802 (WRC- 03), Background Information: In the Preliminary Agenda for WRC- 2010, agenda item 2.2 states: “to consider frequency allocations between 275 GHz and 3 000 GHz taking into account the result of ITU- R studies in accordance with Resolution 950 (WRC- 03);” Studies in the ITU- R, most notably WP1A, WP3J, WP3M, WP4A, WP7B, WP7C, WP7D, WP8A, WP9B, have very clearly identified the interest within the active and passive services in using frequencies in the spectral region above 275 GHz. Resolution 950 (WRC- 03) has allowed for the submission of details on systems operating in this range into the Master International Frequency Register (MIFR). However, there is no registered use to date by any of the active services. On the other hand, the radio astronomy, Earth exploration- satellite (passive) and the space research (passive) services all make extensive use of this spectral region. Within the radio astronomy service, several administrations have already made significant infrastructure investments in radio astronomy sites around the world. This extensive use of this spectral region by the passive services along with the lack of use of the same by the various active services indicates that the general consideration of frequency allocations between 275 and 3000 GHz is premature and such consideration would likely take up a great deal of resources in preparing for the 2010 Conference. As an alternative, reviewing and revising No. 5.565 would be desirable while at the same time require far less preparation by administrations for the 2010 Conference.

X to review and revise No. 5.565 with a view to identifying additional frequencies for passive services in the spectral region from 275 – 3000 GHz, taking into account the results of ITU- R studies in accordance with Resolution 950. Reasons: The extensive use of this spectral region by the passive services along with the lack of use of the same by the various active services indicates that the general consideration of frequency allocations between 275 and 3000 GHz is premature and such consideration would likely take up a great deal of resources in preparing for the 2010 Conference.

USA/ / 4 MOD RESOLUTION 950 (WRC- 0307) Consideration of the use of the frequencies between 275 and 3 000 GHz The World Radiocommunication Conference (Geneva, 2003), considering a) that, in the Table of Frequency Allocations, frequency bands above 275 GHz are not allocated; b) that, notwithstanding considering a), No. 5.565 makes provision for the use of the frequency band 275- 1 000 GHz for the experimentation with, and development of various passive services and all other services and recognizes the need to conduct further experimentation and research; c) that No. 5.565 also makes provision for the protection of passive services until, and if, such time as the Table of Frequency Allocations may be extended; d) that, in addition to the spectral lines identified by No. 5.565, research activities in the bands above 275 GHz may yield other spectral lines of interest, such as those listed in Recommendation ITU- R RA. 314; e) that within various Radiocommunication Study Groups, studies on systems between 275 and 3 000 GHz, including system characteristics of suitable applications, are being considered; f) that the present use of the bands between 275 and 3 000 GHz is mainly related to the passive services, however, with anticipated technology development, the bands may become increasingly important for suitable active service applications; 78 79 g) that sharing studies in ITU- R among passive services and all other services operating in frequencies between 275 and 3 000 GHz have not been completed, recognizing c) that propagation characteristics at frequencies above 275 GHz, such as atmospheric absorption and scattering, have a significant impact on the performance of both active and passive systems and need to be studied; d) that it is necessary to investigate further the potential uses of the bands between 275 and 3 000 GHz by suitable applications, noting a) that significant infrastructure investments are being made under international collaboration for the use of these bands between 275 and 3 000 GHz, for example, the Atacama Large Millimetre Array (ALMA), a facility under construction that will provide new insights on the structure of the universe; b) that Radiocommunication Bureau Circular Letter CR/ 137 identified additional information for the Bureau to record characteristics of active and passive sensors for Earth exploration- satellite service and space research service satellites, in frequency bands below 275 GHz, further noting a) that a process and format similar to that provided in noting b) could be used to record systems operating in the 275 to 3 000 GHz band; b) that recording active and passive systems operating in the 275 to 3 000 GHz band will provide information until the date when, and if, it is determined that changes to the Radio Regulations are needed, resolves 1 to consider at WRC- 10 frequency allocations between 275 GHz and 3 000 GHz taking into account the result of the ITU- R studies; 2 that administrations may submit for inclusion in the Master International Frequency Register details on systems which operate between 275 and 3 000 GHz and which may be recorded by the Radiocommunication Bureau under Nos. 8.4, 11.8 and 11.12, invites ITU- R to conduct the necessary studies in time for consideration by WRC- 10 with a view to the modification of No. 5.565 or the possible extension of the Table of Frequency Allocations above 275 GHz, including advice on the applications suitable for such bands, instructs the Director of the Radiocommunication Bureau to accept submissions referred to in resolves 2, and to record them in the Master International Frequency Register. - FCC - 79
